The San Antonio Spurs have commented on Tim Duncan's injury and Adrian Wojnarowski has tweeted the following:

MRI on Tim Duncan's knee shows no structural damage, Spurs say. He will be day to day. (@WojYahooNBA)

This is a sigh of relief to Spurs fans who were fearing the worst. Duncan may take time off, but knowing nothing serious is going on with his injury will give him for the stretch run for a fifth title.
